Special growth regulator for peanut full fruit period

Abstract

The invention relates to the technical field of peanut cultivation, in particular to a special growth regulator for peanut fruit full stage: chitosan oligosaccharide 5-10g, seaweed extract 50-80g, potassium dihydrogen phosphate 150-180g, thiophanate-methyl 60-70g , 160-235g of sucrose. The chlorophyll content, net photosynthetic rate and root activity of peanut leaves treated with this regulator at the full fruit stage were significantly higher than those of each control, the SOD activity and POD activity of leaves were significantly higher than each control, and the MDA content was significantly lower than that of the control, indicating that The conditioner can effectively remove oxygen free radicals and delay aging; the conditioner significantly promotes the accumulation of pod dry matter and the synthesis of protein and fat in seeds, and plays an important role in promoting yield and product quality.

Description

technical field [0001] The invention relates to the technical field of peanut cultivation, in particular to a special growth regulator for peanut fruit-full stage. Background technique [0002] In the later stage of peanut growth, especially under film-covered cultivation conditions, premature senescence will occur. At the same time, peanut leaf spot is more common. In severe cases, it will cause leaf defoliation and early plant withering, which will affect nutrient accumulation and lead to insufficient pods, reducing kernel yield and oil content. , easy to drop fruit and seeds to germinate when harvested. The problem of premature senescence in the later stage of peanut growth can be solved by topdressing the leaves. However, the single spraying of foliar fertilizer has little effect, and the oxygen free radicals in the body cannot be effectively removed. Therefore urgently need to invent a kind of growth regulator that can not only effectively scavenge oxygen free radical...
